Phylogenetic reconstruction of the Neotropical family Quiinaceae (Malpighiales) based on morphology with remarks on the evolution of an androdioecious sex distribution

Based on morphology, a cladistic analysis of the Neotropical family Quiinaceae (Malpighiales) was performed to generate a hypothesis of the phylogenetic relationships within the family. The monotypic Medusagynaceae and four species of Ochnaceae were used as outgroup. Using equal weights, the Quiinaceae find strong jackknife support and all genera, apart from Lacunaria. are monophyletic. Lacunaria

Nt-proANP in plasma, a marker of salt sensitivity, is reduced in type 2 diabetes patients.

Objective. We recently showed that plasma concentration of N-terminal atrial natriuretic peptide (Nt-proANP) is strongly directly related to salt sensitivity. The aims of the present study were to test (i) whether plasma concentration of N-terminal brain natriuretic peptide (Nt-proBNP) is related to salt sensitivity and (ii) whether Nt-proANP, as a marker of salt sensitivity, differs between type

Borreliosis as a cause of peripheral facial palsy: a multi-center study

Borreliosis is known to be a common cause of peripheral facial palsy in Stockholm and its vicinity. The aim of the present study was to investigate the frequency and characteristics of borreliosis among patients with peripheral facial palsy in different parts of Sweden. All serological tests were performed in one laboratory. Ten Swedish Ear Nose and Throat clinics participated in a prospective 1-y

Oral status, oral infections and some lifestyle factors as risk factors for oral and oropharyngeal squamous cell carcinoma: A population-based case-control study in southern Sweden

Conclusion. Our results show that average and poor oral hygiene and inadequate dental status are independent risk factors for oral and oropharyngeal squamous cell carcinoma ( OOSCC), irrespective of tobacco and alcohol consumption. Objective. To evaluate a possible relationship between oral cancer, oral hygiene, dental status, oral mucosal lesions and some lifestyle factors in a population- based

Effects of soil pH and phosphorus on in vitro pollen competitive ability and sporophytic traits in clones of Viola tricolor

Greenhouse-grown clones of Viola tricolor were used to evaluate the importance of genetic effects on in vit ro pollen tube growth rate in relation to the influence of two environmental soil factors-pH and phosphorus content. After 1 mo in different soil treatments, individual pollen tube growth rate was affected by a genotype by phosphorus interaction, while it was unaffected by either main effect

Doubly ionized thorium: Laser lifetime measurements and transition probability determination of interest in cosmochronology

The first lifetime measurements have been performed for six levels of doubly ionized thorium, an important cosmochronometer in astrophysics for estimating the age of the Galaxy. The levels, belonging to the 5f(2), 5f7p, 7s7p, and 6d7p configurations of Th III, have been measured by the time-resolved laser-induced fluorescence method and compared with relativistic Hartree-Fock calculations includin

Essays on Capital Structure

Chapter 2 analyses the relationship between capital structure and industry classification of Swedish firms. This study also analyses the determinants of the capital structure at the industry level. Since the assumption required for a parametric analysis of variances are not satisfied, a nonparametric method is applied to test for cross-industry differences in capital structure. The results show th

Emphysematous lesions and lung function in healthy smokers 60 years of age

We aimed to study the occurrence of emphysematous lesions in symptom free smoking men of about 60 years of age and in a matching group of never-smoking men and the relationship between pulmonary changes at high resolution computed tomography (HRCT) and lung function tests. Our investigation included 57 smoking and 32 never-smoking healthy men from a randomized epidemiological study. HRCT was perfo

Women's Human Rights and Islam : a Study of Three Attempts at Accommodation

Popular Abstract in Swedish Avhandlingen tar avstamp i en pågående internationell diskussion om kvinnors mänskliga rättigheter och islam. I denna diskussion kan olika muslimska ståndpunkter identifieras. En del avvisar mänskliga rättigheter, såsom dessa formulerats i internationella människorättsdokument, som ”västerländska” påfund och hävdar de religiösa källornas överordnade auktoritet. För andrThe dissertation focuses on interpretations of Islam that claim compatibility with international human rights norms in the context of women’s rights. These interpretations are seen as parts of an on-going contemporary international debate on women’s human rights and Islam that engages Muslims as well as non-Muslims. Existing UN-formulated international human rights schemes are a basic starting poi

The novel IgD binding protein from Moraxella catarrhalis induces human B lymphocyte activation and Ig secretion in the presence of Th2 cytokines.

Moraxella IgD binding protein (MID) is a novel bacterial outer membrane protein with IgD-binding properties. MID was purified from the respiratory pathogen Moraxella catarrhalis and is here shown to have B cell stimulatory properties. Purified MID in the range of 0.01-0.1 microg/ml was optimal to induce a proliferative response in human PBL. MID coupled to Sepharose and formalin-fixed M. catarrhal

Term breech delivery in Sweden: mortality relative to fetal presentation and planned mode of delivery

Objectives. To compare perinatal and infant mortality in breech and cephalic presentations and between planned vaginal and cesarean section (CS) breech deliveries in Sweden. Methods. The study comprised two parts. Study A is a national cohort study for the period 1991-2001, including 22 549 breech presentations and 875 249 cephalic presentations born at >= 38 completed weeks. Study B is a case-con

Amperometric screen-printed biosensor arrays with co-immobilised oxidoreductases and cholinesterases

Amperometric screen-printed biosensor arrays for detection of pesticides (organophosphates and carbamates) and phenols have been developed. Cholinesterases (AChE and BChE), tyrosinase (TYR), peroxidases (SBP. soybean and HRP. horseradish) and cellobiose dehydrogenase (CDH) were combined on the same array consisting of one Ag/AgCl reference electrode surrounded by eight radially distributed working

On fire flames out of vertical openings

Some recent Swedish data on compartment fires are reviewed. Measured burning rates were as high as 7.7 A √ H kg/min where A is the opening area in m² and H is its height in m. A conventional power law is shown to relate the burning rate and the measured external flame length as well as does an empirical proportionality. The corrections to be allowed in both methods for the burning within the compa

Ion channels, electrical activity and insulin secretion

The insulin-secreting pancreatic beta cell is electrically excitable and changes in the membrane potential play an important role in coupling the metabolism of glucose (and other nutrient secretagogues) to the discharge of the insulin-containing granule. The application of the patch-clamp technique, which permits the recordings of the minute currents associated with the opening of individual ion c

Autofluorescence of various rodent tissues and human skin tumour samples

Fluorescence spectra from different organs in rats and mice have been recorded to explore the potential of non-intrusive tissue diagnostics. The fluorescence was induced by a nitrogen laser that emitted at a wavelength of 337 nm. Optical multichannel techniques were used for the detection. Spectra are given from 19 different sites in Wistar/Furth rats, including an inoculated malignant tumour. The
